What is trigeneration and what benefits does it provide? At Keyplan, we are experts.

At Keyplan, we are experts in the projection, development and construction of cogeneration and trigeneration plants.

Cogeneration consists of obtaining heat (thermal energy) and electricity (electrical energy), through a primary source of energy. This results in great efficiency and cost reduction.

In the case of trigeneration, we also get cold, thus greatly reducing energy costs in production processes, and specifically in industry or large buildings, such as large hotels in which in addition to the need for heating and electricity, they need important amounts of cold for air conditioning.

Trigeneration plants are usually composed of a cogeneration plant, and an absorption system for cold. For this, plants with alternative engines or gas turbines are used. In the first case, with alternative engines, energy is generated through the combustion of a fuel. In the case of gas turbines, although the performance is lower than with the previous system, it is easier to recover heat since it is concentrated, and they can be of single or combined cycle, depending on the use of concentrated steam.

Without a doubt, trigeneration plants have great advantages such as:

  • Reduction of greenhouse gas emissions.
  • Reduction of energy leaks.
  • Therefore, competitiveness grows and reduces costs.

Its implementation is very interesting and necessary for high demand industries of heat, cold and electricity, as well as, as we said earlier, facilities and buildings with a high consumption of these.

Recently, in Keyplan, we have installed in a large hotel complex in the Dominican Republic, a trigeneration plant to distribute heat, cold and electricity to 1,200 rooms and their services.
